“Two occupants were found trapped inside one of the segments,” Ottawa paramedics said. Firefighters had to extract the two men inside.

A 27-year-old man was in cardiac arrest, and was pronounced dead at the scene after attempts to resuscitate him.

The 20-year-old suffered “critical injuries to his lower extremities” but remained conscious. He was initially listed in serious condition, but on Saturday evening police said he was in stable condition.

Police are investigating and continuing to seek witnesses to the crash. Anyone with information is asked to call Ottawa police at 613 236 1222 ext 2481 or Crime Stoppers at 233-TIPS.

The age of one of the men in this story was updated after paramedics had initially said it was a 19-year-old in the collision. Police say the man is 20.
